Inflorescences rudimentary 1-headed racemes with axes less than 0.5 mm long and brown bracts persistent at base; peduncles 1–4 mm long; heads globular, 30-flowered, golden; bracteoles dark brown, slightly exserted in buds. Flowers predominantly 5-merous; sepals free or partially united, linear to linear-spathulate, sometimes unequal.
